'Thickness' in the Bible

And, behold, a wall on the outside of the house round about, and in the man's hand a measuring reed six cubits long, of a cubit and a handbreadth each: so he measured the thickness of the building, one reed; and the height, one reed.

The thickness of the wall, which was for the side-chambers, on the outside, was five cubits: and that which was left was the place of the side-chambers that belonged to the house.

In the thickness of the wall of the court toward the east, before the separate place, and before the building, there were chambers.
